which "reduces translation btwn the 2 bones" & are also held together by proximal & distal radioulnar joint

what inserts on the coronoid process?

brachialis tendon

occasionally the flexor pollicus longus

tricep tendon attaches to:

olecranon

attachment of the brachialis tendon:

ulnar tuberosity

head of radius articulates on:

radial notch

the end of the head of the radius articulates with the:
the rounded part of the head articulates c/:

capitulum

ulna & partly c/ the ligaments that surround it

what attaches the distal radioulnar joint to the radius and ulnar styloid?

triangular cartilage

during movement assoc with supination & pronation of the hand, the _____________ rides around the ___________ with the _______ providing the pivot point.

distal head of the radius

head of the ulna

ulnar styloid

wrist joint is made of what 2 joints?
what are their functions?

radiocarpal joint: radial & ulnar deviation

mid carpel joint

both: flexion & extension of the wrist

what are the 8 carpel bones in order?

trapezium

trapezoid

capitate

hamate

scaphoid

lunate

triquetral

pisiform

what are the 3 ligaments of the wrist?

radial collateral ligament

anular ligament

ulnar collateral ligament

which ligaments of the wrist are laterally placed?
what do they do?

radial collateral ligament

anular ligament

holds the radial side of the elbow together

what muscle arises from the radial collateral ligament?

supinator

radial collateral ligament attaches from the:

lateral epicondyle & "fans out" continuous c/ the anular ligament

anular ligament conforms entirely to the:

radial head so that the radius, although ALLOWED to rotate, is completely limited otherwise

the ulnar collateral ligament arises from:

the medial epicondyle "fanning out" in a triangle attaching to the ulna all along the medial side of the trochlear notch

is the joint capsule of the elbow stable or not stable?

VERY STABLE

(ligaments & bony articulation)

what joints are referred to as 1 joint (elbow joint) bc they are located in the same anatomical region & not entirely separated structurally?

Humeral ulnar joint

proximal radioulnar joint

what 2 joints are close together but are physically separated?

distal radioulnar joint

wrist joint

describe the appearance of the elbow joint:

relatively loose, thin, & baggy ant & post

this allows FROM

what is a difference btwn the elbow joint and the wrist joint?

elbow stability is related to osseous structures

wrist is stabilized & held together ENTIRELY by ligaments

the capsule of the wrist joint is strong & represented on the extensor aspect as the _________ & on the flexor aspect, it forms the:

Dorsal radiocarpal ligament

Palmar radiocarpal ligament

collateral ligaments hold bones together in:

radial & ulnar deviation

radiocarpal ligaments hold bones together in:

flexion & extension

3 flexor muscles of the forearm:

*note: all of these muscles funct: is flex the forearm. and a little supination

brachialis

biceps brachii

brachioradialis

attachment of brachialis:

arising from broad area on the ant humerus & is inserted onto ulnar tuberosity

attachment of bicep brachii-
long head:
short head:
on its lateral edge, the tendon fans out medially into a thin sheet of fascia called ________ which is continuous c/ deep fascia that surrounds the forearm
